IMPROVEMENT IN TRU NK-FASTENINGS.

The Schedule referred tu in there Letters Patent and making part of the same.

I, Louis RANsoM, oi Lansingburg, in the county of Rensselaer and State of New York, have invented certain Improvements in Trunk-Fastenings, of which the following is a specification.

Nature and Object of the Invention.

vthis button also forming a lock.

The whole fixture is so constructed as to he laid on the surface of the trunk without cutting into it, thereby weakening the lumber, as is the case with most trunk-locks.

Description of the Accompanying Drawing.

Figure 1 is a front view or elevation of my invention, the fastening being closed and locked.

Figure 2 is a side elevation of my invention, the fastening being closed and locked.

I Figure 3 is a perspective view of the same, showing the construction and operation of the toggle-joint.

Figure 4 is an enlarged or full-sized view of the under side of the button forming the lock.

Figure 5 is a section of the same button through the line l 2. l

Figure 6 is a view of the upper side of the button.

Figure 7 are screw-heads forming one variety of lock.

Figure 8 is another form of button so constructed as to form a lock.

Figures 9 and 10 are sections of the button-lock, g. 8, through the line 3 4, showing the structure and operation of the said lock.

Figure 11 is the key of the button-lock.

Figure 12 is a variation of figs. 1, 2, and 3, the toggle-joint being formed in a manner different from the iirst.

Figure 13 is still another way of constructing the toggle-joint, two tongues being used instead of one.

General Description.

a b c are plates of metal hinged together, as represented in figs. 1, 2, and 3-c being secured to the trunk-lid, b and c swinging loose.

The plate c has a part, q, removed to give place to the tongue d.

Another plate of metal, f, is made fast to the body of the trunk, and has the tongue d secured to it by a joint at c, upon which it swingsfreely, a space being cut away for it in. this plate also, thatthe tongue may lie ush with c, or nearly so,vwl1en the fastening vis closed.

This toggle-joint may he formed by hiuging the tongue d to the plate c at t, letting its free end rest against a projection in the plate f at c, (see tig. 12;) or it may be formed by hinginga tongue, n n, to each side of f to act against corresponding projections in the plate c. (See g. 13.) y

T T indicate the dividing line between the body and lid of the trunk. Y

gis a button, consisting of tivo disks made of unequal diameters and placed eccentric to each other. This fastens down the toggle-joint ,by being turned partly around so the projecting part of the upper disk laps'over the plate c, thus preventing its rising. (See fig. 8.-) The button is keptin place byasimple screw having a slot of peculiar and varied form in the head, (see iig. 7,) so that a screw-driver` made to lit becomes a key.

This screw may he further protected by sinking it into a chamber, as at i, figs. 5 and or the fastening may be securely locked by the button-lock represented at figs. 8,9, and 10.

This button-lock is constructed and operated in the following manner:

g is a button, full size, with a boss formed at Z for a hinge. A slot is made in this button, having parallel sides and a section, whose shape is indicated by the deeply-shaded part s, tig. 10.

The latch k is hinged into this button at Z, and the smaller tongue n is hinged into the latch 70, apart from Which it is crowded by a minute spring, of rubber or any suitable material, inserted between them.

Fig. 10 represents this apparatus unlocked. In order to lock it the latch It is pressed down into the slot made to receive it, when the tongue n lshuts doivn,

with its free end butting against the square Sironider r.

It is evident that the latch k cannot be raised until the free end of n is raised above the shoulder against which it abuts. This is done by passing the key, iig. 11, under it through the key-hole m and lifting over ll.

When It is closed its lower limb at p projects through a slot in the bottom plate j', thus arresting any motion in the button; butwhen open, as at iig. 10, this part being out of the slot, the button ma Y be revolved freely.

The manner of operating my invention is as follows:

Close the trunk. Then set the plate c at the bottom of the slot q into the fork of the tongue d. (See iig. 3.) Press the plate c down upon f, iig. 2. Then turn the button g into position, turn down the screw fi, or close the tongue k, as the `ease may be, and the trunk is firmly strapped, buckled, and locked.

If the trunk be sov full that it4 will not close easily,

the toggle-joint will vbring it readily into place and holdv it there.

Iclaim as my invention* 1. The double-hinged plates a b c and the tongue d, forming, a toggle-joint, 4in combination with the cam-button g 'provided with a keyed screw or other suitable locking device. f v

2. ,The slotted plate c, doublehinged to the part a by the intervening plate b, the tongue d, and slotted plate f carrying the cam-button y, all arranged and operating substantially as described..

` 3. The combination 'of the cam-button g and hinged latch k, 'provded with' a key-hole, fm, and a suitable spring, with the tongue n and slotted plate f, to form' 'EDWIN ADAMs, A. SAEAMAN.
